the mass was first cut by the Foote Co., two fragments for specific grav- 

 ity determination and three for chemical study. The last, aggregating 

 about 50 gm. in weight, were sent to Booth, Garrett & Blair of Phila- 

 delphia for analysis, with the following result : 



Per cent 



Fe (by difference) 92.376 



Ni 6.980 



Co 0.505 



Cu 0.018 



S 0.014 



P 0.099 



Si 0.008 



The analysts report the apparent presence of a trace of some other 

 element, probably of the iron-platinum group of metals, but state that 

 they were unable to isolate and determine it in the amount of material 

 available and that it must be present in variable quantities. 



The specific gravity as determined at the American Museum on a 

 fragment weighing about 12 gm. is 7.63. This is a low value, even when 

 the small percentage of Ni -\- Co present is taken into consideration. 



End piece No. 1 contains the angular hole left by breaking out the 

 fragment for assay. As submitted to me, this piece was about 40 mm. 

 thick and weighed 1174 gm. The Widmanstatten lines (PI. XXXVII) 

 were traceable over the whole polished and etched surface, but they 

 were obscured by a flecky granulation extending likewise over the whole 

 surface. The flecks, whose appearance reminds one of the particles 

 making up a flocculent chemical precipitate, are irregular in outline and 

 are from 0.4 to 0.5 mm. across, seldom reaching the latter dimensions. 

 They have no particular orientation and are so strongly developed in 

 places as to suggest an approach to ataxitic structure. This portion of 

 the mass closely resembles Tazewell in appearance. The etched surface 

 of slice No. 1 was about 13 mm. distant from that of the end piece. It 

 showed the flocculent granulation over about three fourths of its surface 

 (PI. XXXVIII), the remainder being occupied by a subcentral oval 

 area about 90 x 40 mm. in size in which the kamacite was practically free 

 from granulation. In the succeeding slices, the oval clear area ex- 

 panded until in slice No. 6 there was no granulated area (PI. XXXIX). 

 End piece No. 2, however, showed a bright fleck here and there. The 

 granulated portion of the mass, therefore, originally formed a cap over a 

 roughly cone-shaped development of iron that was practically free from 

 the flecks. 



Turning now to the other features of the meteorite we may say that 

 the Widmanstatten lines are well developed, forming kamacite bands
